An assessment of creativity style inventory: A Rasch model

Abstract

This study aimed to develop a version of the Creativity Style Inventory (CSI) that is suitable for contexts where participants have limited time. Specifically, it sought to validate an adapted CSI for Indonesia and classify the difficulty levels of its items. The research involved assessing the creativity of 507 secondary school students from Lampung province, Indonesia, comprising 53.3% female and 46.7% male participants, with an average age of 13.72 ± 0.74 years. The Rasch measurement model was utilised and analysed using Winsteps software to evaluate responses from a CSI and personality inventory. The results indicated that the CSI met the content and construct validity, and reliability standards according to Rasch parameters, highlighting its significance in educational settings. A Differential Item Functioning (DIF) analysis revealed that only one item fell into the moderate to large DIF category. Additionally, the findings demonstrated notable demographic trends, with female, suburban, and public school students exhibiting higher levels of creativity style. This study emphasizes the need for culturally relevant assessment tools like the CSI to inform educational strategies and policies designed to enhance creativity. Ultimately, the adapted CSI has been validated as a reliable instrument for assessing creativity among Indonesian students, reaffirming its importance in educational contexts.
